| Abstract: | Ho3+ and Yb3+ co-doped gadolinium sodium tungstate Ho,Yb:NaGd(WO4)2,Ho,Yb:NGW] single crystal was grown by medium frequency induction Czochralski method. A suitable crystal growth process parameters were en-sured with the pulling speed of 1~2mm/h,the speed of 20~22r/min and the cooling rate of 10℃/h. The IR and Ra-man spectrum of Ho,Yb:NGW crystal have been measured at room temperature, and the assignment of vibrations is discussed. The results of fluorescence spectrum showed that the fluorescence emission of crystal located at 1.90~2.05mm region which is zonal continuous distribution. The strongest fluorescence emission located at 2043nm, which corresponding to the 5I7→5I8 transition of Ho3+,and the full width at half maximum (FWHM) is about 100nm. |
